An exploration into my work hours location tracking on my iPhone and the service IFTTT which logged the days and times I left my office each day into a Google spreadsheet.

But first data!

Overall, data was collected on 629 days.

Data collection was going well until the end of 2019! 2020 and 2021 was disrupted by COVID. There were then some periods of time when the GPS logger was not activated.

But from May 2024, I have been reliably tracking my arrivals and departures from work each day!

More varied start or finish times?

My start hours appear more consistent than my finishing hours, with most days starting off before 8am.

The hours I finish work are more varied, with most days ending after 5:30pm but sometimes very late.

Does it matter what the month is?

Looking all the days from the same month over the last few years, there seems to be a pattern of working longer than eight hour days.

July and December are “lighter months” as these are the bigger breaks between teaching semesters, and so I am either overseas at conferences or on annual leave.

But remember, this is just the hours logged at work ….

In conclusion

Overall, I learned that I work too many hours.

But I love teaching, doing research related to data science and educational technologies, and creating things with code.
